Question

5 Assertion (A): An object can have constant speed but variable velocity.
Reason (R) in a uniform circular motion, speed reamins unchanged
​

Answer 1

Answer:

true

Explanation:

we say only object is accelrating because of change in velocity as direction changes at every instance

Answer 2

Answer:

In circular motion the speed of object is constant but velocity is not constant

Explanation:

as velocity of a body is a vector quantity and in circular motion it keeps on changing its direction.. so velocity keeps on changing.
